Add an option to spellcheck and grammarcheck the OCR fields and product name using OS level systems

[Pierre Slamich]

Problem

• We have an ongoing effort for ingredient spellcheck
• Some other fields (like product name) might benefit from OS-level spellcheck and grammar check.

Proposed solution

• Add an option to spellcheck and grammar check the OCR fields and product name using the OS-level systems
• Make it optional (dev mode) so that we can evaluate performance and impact

Part of

• #503

Could you describe what you mean by spellcheck/grammar check?
Is-it the red lines in text fields? If yes, true, this is already available in Flutter and is just a parameter to add.

If you want a real automatic spellcheck, there are some solutions, but they force storing a dictionary of words per language.
